E'OUTBALL GAME APPARATUS,

Application filed. January 24, 1924. Serial No. 688,282.

To ZZ who/fn it' may concern: stitution of team members by the players as Be it lrnoivn that I, HUGH ROBERTSON, a is the case in regulation toot-ball. citizen of the United States, residing at Other objects and advantages of the in- 55 lilast Milton, in the county oiu Norfolk and veiition relate to various novel details ot ar- State of lvlassachusetts, have invented cerrangement ot' the parts and methods ot tain new and usetul improvements in Footmanipulating the saine as Will be more fully ball Game Apparatus, ot which the follow" set torth in the detailed description to toling is a specitication. low. 60

This invention relates to an improved Referring to the drawings: toot-ball game wherein the interest of the Fig. l represents a board or card upon players and the instructive qualities of the which is laid out a toot-ball playing field as gaine are enhanced by the provision of a. used in regulation :toot-ball.

plurality ot diti'erent team charts representl? 2` represents a pair of dice, one of 65 ing teams possessing markedly different otwhich is White, the other being colored so l5 t'ensive and defensive powers. that it may be readily distinguished from The principal object ot the invention is the former. to provide an interesting form` oit game Fig. 3 is a. detail vieW of the Jfoot-ball which may be utilized by coaches and others used in playing the game. 70 versed iii the technical. details ot modern lF #t shows a ruled sheet having placed toot-ball as a means t'or instructing players thereon numbers and indicia relating to an and others iii the gaine and in the class of imaginary toot-ball team which may be desplays which may be employed to advantage ignated by a. Certain name and Which in the under ditlferent conditions oi' play. present instance is called Cavalier College. 75 Another object oit the invention is to prolFigs. t3, and 7 shoiv ruled sheets simvide a game ot this character which may be iiar in t'orm to that shovvn in Fig. 4, but utilized by Ltoot-ball coaches and others to containing numbers and indicia differing instruct players and those not fully versed from that shown on the sheet illustrated in in the rules oi.j the game concerning the vari- Fig. si, as vvell as from each other, each of 80 ous penalties imposed by the rules and the the sheets shown in these Vtigures represent- 3o extent or amount ot distance to be given ing an imaginary toot-ball team, the teams to the team opposing the penalized team by being designated as lVinchendon University, reason ot such penalty, as Well as the cir Jeiterson University and Alton University, euinstaiices under which penalties are imrespectively. 85 posed by the rules. Fig. 8 shows a sheet on which appears a Another object ot the invention is to maire table et explanations ot the abbreviations the game more interesting and instructive and indicia appearing on the team sheets,

The team charts preferably represent teams which dill'er from each other in that. some of the teams are strong,` in one departn' ent of the gaine and ivealr in others While each presents characteristics of strength and Weakness which diiter in kind and degree from each ot the others.

While various forms of indoor toot-ball gaines have been employed hereto'iore no means has been providedj so tar aware, for utilizing different imaginary teams ditiiering from each other in charact ristic strong' and Weak plays, and no gaine o this character has been provided wherein team charts were provided for determining,l the results ot individual plays in connection with a certain specified team. The employment ot team charts adds greatly to the interest in the game also by reason ot the Ytact that the di. .tances ga ned or lost may be dependent to some ent-ent upon the element o1 lucl; v-hile depending; in the main upon the choice of plays which utilize to the greatest degree the strong features ot the particular team.

@ther features in which the present game ditlers radically from those heretofore employed comprises the provision ot team chai ts in series or sets which include different. penalties or a different combination ol' penalties and the provision ot substitute charts whereby the players may, as permitted by the rules of regulation foot-ball substitute different members ot their teams, which adds greatly to the interest ot the game.

The playing field l as shown in Fig'. l mauv be laid out on a board or cardboard strip Q, the lield being marked oil by equidistant lines each ot which is designated by numbers placed .it opposite ends thcreo'l" t.;- cept the goal lines which are indicated by G, and the center line which is designated HC.

rllhe lines 3 represent the live yard lines the playing lield the center7 or lilftythe side lines and located ri the one-yard lines of the tield, so that the ball can be positioned so as to sii'nulatc its position in aetual play.

rlhe goal posts 'Y are located at opposite ends olf the i'ield7 and linesinans stakes 8 are provided, connected by a cord or cable 9, the linesmans stakes 8 being,` adapted to be placed in the proper position in the holes located on either side ot the playing` held to marl-t the position of the ball when put in play or a'litor a first down.

The 'toot-b: `ll l0 is in the forin ol a` spheriod and is provided with a post ll which n' be placed in et the holes lor t on 't playing lield.

rllhe dice shown in Fig. 2 are oi" the usual torni but distinquishable :troni each other by their coloring., 'the die i3 being; colored blue in the present instance, -vhile the die el is White. lt is et course to be uriner-stood that any different colors may be employed as desi 1ed which vill distinguish the dice trov each other. lfhe numbers from l to (l are shovvn on the faces of each die and arranged in the usual manner.

The goal posts 'Z shovvn o sitioncd on cach goal line foot-ball, but perform no rame other tlan to give the n l the appearnce of the regulation Atoot-ba l field. The ole." extending alonscg` the center line ort o. may be used to receive the post Yll a )orting the ball or the holes G may be nployed for that purpose, the addition ot .e holes permitting the ball to be placed t diilerent points transversely ol the lield s in actual playing` conditions. 'llho lincslans posts 8 are connected by a cable or cord ol suitable length to extend across the spaces between ten ol the holes 5, whereby ene ot the posts may e placed opposite the position the ball when it is put in play or Vwhen one team surrenders the hall to the other, and the other post may be placed in the tenth hole theA etrom to indicate the distance Which must be `mined in tour phys: Vto

The tean'i charts as shovvn in lilies. G and 7 are each ruled to provide eleven tical. columns and` thirty-six horizonte-.l in addition to spaces at the top column tor denoting the play. columns are designated as tollou's troni to right:sig rais, gua d ruslnl taclrl ci run, lioiavard passi plug' punta run bach punt,H Lynincl; on, L and held Goal.7l

S, shows a table ot explanations ,(5 j (ll. abbreviations or other indicia found l ll the columns under the plays designated in Figs. 4, 5, 6 and 7, and is ruled to form a vertical column at the lett oiv the ligure and horizontal lines extending across the sheet. The abbreviations noted are placed in the vertical column at the lett and the explanations are placed opposite the respective abbreviations in the horizontal lines.

For the purpose of illustration it may be assumed that A and B are to play and that they draw team charts at random or select lli/'inchendon University and Cavalier College teams respectively without being given an opportunity to study the charts oi' their respective teams. Since A is to use the llVinchendon University team and B the Cavalier College team, the team chart or lllfinchendon University as shown in Fig. 4, is given to B yand the team chart of Cavalier College as: shown in Fig. 5 is given to without i being given any opportunity to study the team chart ot Vllinchendon University and without permittingl B to eX- amine the team chart of Cavalier College. ln this way each player is kept in ignorance ot the strong and weak characteristics of his own team until he is able to develop these features by properly selecting his plays during the progress of the game.

rl`he players then place the board shown in llig. l between them and toss a coin to determine which side shall have the choice oiE goals.

Assume that A Wins the. toss and chooses to defend a certain goal. B chooses to kick oft.

rlhe football is placed in positionv with its post in the hole on the 40-yard line of the board nearest Ythe goal B dfends.

B then throws the dice and reads-the num: bers which tal-l uppermost, the blue die being taken to indicate the l'irst numeral and the white `die thesecond numeral oit' the signal number. When B makes his throw and the numeral 2 is designated by the blue die and the numeral 5 by the whiteV die, which calls for Athe number 25 on the chart. who has charge of the team chart for Cava-lier College then follows down the signal column. to the number 25 and across to the column designated kick oil and reads 50 yards. B then advances the toothall to the lll/Yinchendon University ten-yard line.

A then throws the dice and it he throws 2l, B taking the chart oi llv'inchendon University, iinds the nun'iber 21 under signals and following the horizontal line across to the column designated run back kick oil reads 20 yards. A then advances the ball to his teanis thirty-yard line and the linesmens posts are put in position one on the thirtyyard line and the other on the 'forty-yard line. lt is now iirst down for 1Winchen` don University on their own thirty-yard lline. Examination oit the chart will show that A now has a choice ot six plays which he may use namely: guard rush off tackle end run forward pass trick play7 or punt. lle does not at this point know the strong and weak offensive feature ot' lllinchendon University but must endeavor to ascertain these ifacts by iinding the results obtained by trying certain plays. 0f course, according to the chart it. might also at this point try for a goal trom the field but this would be contrary to proper tootball practice in the position ot his team and an examination oit the chart will show that such a play would prove to be a. failure at this point as would. be the case in regulation football.

JLBet us assume that A decides to try a guard play. lle calls cguard rush`7 and throws the dice indicating theviunnber 3G. B who has the team chart reads oil' the distance which is l yard. A decides to tryY a play ott tackle and calls out oil tackle, at the saine time throwing the number 35 with the dice. .l reads oil the distance from 'the chart and linds the indicia H. l). Upon relerence to the table ot explanations shown in Fig. 8, he iinds that ll. l). denotes holding by defensive line, penalty 5 yards and lirst down. This advances the ball live yards and makes it iirst down on lllinchendon University thirtyssix yard line. The .linesniens post-s are advanced to the thirty-sii: and 'forty-sii; yard lines respectively and play is resumed. A may decide at this point to try an end run and calling end run he throws the dice and the throw designates l.the numlber 3l. B readinsr Yfrom theV chart finds that A has lost G yards. rlhe hall is then placed back on the thirty-yard line and it is second down with sixteen yards to gaia. ri decides to try a trick play and throws the dice for the number 55. B finds upon relerence to the chart the indicia U., and by referring to thel table of explanations secs that l?. U indicates fumble unrecoveredother teams ball.

The linesmens posts are then changed to the thirty and twenty yard lines and it is Cavalier Colleges ball on its opponents thirty yard line. B now takes the dice and decides to try al play ott tackle. He calls oft tackle and throws the number 31. A new refers to the team chart of Cavalier College and calls the distance as 4 yards. B advances the ball to the twenty-six yard line and decides to try another oli? tackle play. He calls ofi tackle and again throws the dice which indicate the number 46. A upon reference to the chart gives the distance as 4 yards. rlhese plays having been successful B naturally decides to con tinue ed tackle plays and repeats throwing the number 42. A upon reference to the chart finds the distance gained to be 3 yards CTI which makes first down for Cavalier Gollege on its opponents nineteen yard line. The linesmens posts are advanced to the nineteen and nine yard lines and play is resumed. rlhe three preceding plays indicate te il that Cavalier College is probably strong in oli' tackle pla-ys and he naturally decides to continue thesel plays for a touchdown. He calls off tackle and on throvving the dice throws the number all. B reads the distance from the chart as yards which advance the ball to the lllinchendon Universie.v fourteen yard line. .il again tries an oil tackle play and throws the dice throwing the number l upon reference to the chart finds the indicia 0. 0. which,

upo referr' ig to the table of explanations, he s means "Ull'sidc oli'ensive tcani-- p1; y -yards saine down. This carries the ball back to the nineteen yard line making it second down for alici.' College -with ten yards to gain. B continuing pla-y again trays olf tackle and throws the number 32 which A finds gains 3 yards. The ball is advanced to the sixteen yard line and on the saine play being again tried l?) throws #f3 for another gain of 3 yards Which places makes it fourth down on the thirteen yard line with four yards to gain.

rlhis distance is rather more than B can expectto make on an off tackle play and thereis no object in puntino'. He has the choice of a forward pass, trick play or goal from the lield. Let us assume that he tries the latter and throws the number 51. A upon reference to the chart finds the indicia G-l, which upon reference to the table he finds means that a field goal was scored if the ball was Within the fifteen yard line. l; has therefore scored a goal from the field as the ball was on the thirteen yard line.

The game may then be resumed in the usual Way.

rlfhe above description serves to show the manner `of playing the game and also illustrate some of the possibilities for the players to exercise their knowledge of foot-ball as vvell as to learn from an instructor the proper tactics to employ under given conditions, and ascertain by trial the strong and vveak points of their teams.

ln the previously described play A was unable to find Where his team had sufficient c ensive povfer to overcome his opponent ivhile B, on his first play, gained a sufficient distance to indicate to him that department of the game in which his team was able to overcome the opposition. This Was confirined upon his repeating the play, and but for onev unfortiniate play he would probably have been able to score by continued adherence to the olf tackle play.

may be stated that the teams which are included in this description possess the following offensive characteristics. Cavalier College is strong in plays off tackle, punting and lield goals While relatively Weak in trick plays and end runs and very Weak in guard plays, llfinchendon University is very streng in forward passing, average in field goals weak in guard, tackle and trick plays, and very Weak in end runs; Jefferson lniv-'ersity is strong in punting and on end runs, average, in plays ofi' tackle, and Wea-k in forward passing, trick plays and plays through guard; Alton University is very strong at forward passing, strong on olf tackle plays, fair in punting and Weak on end runs and plays through guard.

.ik player in playing this game is placed in the saine position as quarter-back on the playing field in that he is called upon to analyze and determine the strong and Weak points of his own team and use those plays which he finds most effective.

illditional team charts similar to those shown in l" l, i), (i and i' are to be provided, prei ily in sets and each set may be provided with a table of explanations chart, the team charts and table of explanation chart of eat" set being similar to those shown herewith, c cept that the team charts and the table of explanations chart furnished with each set may contain different penalties from those embodied in the team charts and tables of explanation provided in the other sets, and of course the strong and vveak features of the several teams Will ditiier from each other. rthe team charts of other sets or series may be provided with the same numbers of columns and lines of numbers and indicia as those shown herewith, or other and different plays may be added and the table of explanation of each set will be provided with a column at the left for the indicia and lilies extending` to the rie'lit thereof for the explanation of the abbreviations as in the chart shown in Among the penalties provided by the rules in regulation foot-ball ivhich may bc embodied in the additional set or series are the following:

Interference with fensive team,

nter-ference with forward pass by offensive team,

llonghing the kicker,

l'nterfereiu'e by opponent before ball is putin play,

fr player in motion tovvard opponents goal before ball is put in play,

Coaching from the side lines,

Player making fair catch advancing the ball more than tivo steps,

Forward pass handled by ineligible player of the passing side, etc.

Each set or series may comprise, for eX- ainple, a plurality of team charts as illustrated herewith in Figs. 4, 5, 6 and 7, and

forivard pass by dea table of explanations chart as shown in Fig. 8. rllhe sets or series may differ from each other in t kind of penalties introduced as, for example, the more common penalties may be introduced into the lirst set or series, less common penalties in the second set, still more unusual penalties in the third set, etc., thus providing a plurality of sets or series in which the effect of various penalties are taught commencing with those which are` best known and conn cluding with the more unusual and less frequently encountered penalties whereby in playing the game the players will be taught the various penalties imposed and the distance imposed upon the penalized team. In using the game players may begin with the first series and employ this until they are fully conversant with the penalties imposed therein and then use the second series until they learn the results of the penalties taught in the second series and so on through the entire number of series.

It is to be understood that the game follows in all respects the rules of regulation foot-ball and the penalties imposed under the rules, while each series or set may include diiferent penalties they may also include certain penalties common to all, and the team charts of the different sets or series all diifer from each other in points of strength and weaknesses to add interest to the game as well as to instruct the players in analyzing and determining the strong and weak points of the opposing team from the extent to which they are able to gain or lose by employing certain plays.

Figs. 9 to 20 are substitute charts which may be used by the players: for substituting under proper' conditions new players as is the case in regulation foot-ball. In substituting for guard and tackle plays the substitution would occur in the line, for end runs, new ends would be called in, and for forward passing or trick plays a backfield player versed in such a type of play would be brought in, while for field goal a player trained for this type of play would be substituted.

The use of these substitute charts may be illustrated in connection with the play previously described.

Let us suppose that in the play previously described A later acquires the ball on his own 0r `Winchendon University thirty yard line. From his previous experience he has not been able to gain consistently with any play and he may decide that his team is fairly weak in all departments. He may, therefore, declare that he will put in substitute fast backs for running ends. He then chooses, at random and without being permitted to study the charts, one of the charts shown in Figs. l5 and 16. Let us assume that in making this choice he happens to choose the chart shown in Fig. 15. This chart is then substituted temporarily for the end run plays shown on the team chart of lVinchendon University, and B takes this chart shown in Fig. 15 together with the team chart of llilinchendon University, while A, after placing the linesmens posts on the thirty and forty yard lines of illinchendon University, throws the dice to designate the number 25, and calls end run. B follows down the chart shown in Fig. lato 25 and reads the distance as 6 yards. A advances the ball to lVinchendon University thirty-six yard line and again calls end run]7 throwing the number 35. B following the end run chart shown in Fig. l5 calls the distance as 4L yards, making it first down for linchendon University on its own forty yard line.

From the above it will he seen that by substituting and luckily drawing strong end players, A has converted his somewhat weak llinchendon University teamv intoi a` team fairly strong on end runs.

Any suitable rules governing the substitution of players as above described may be adopted not inconsistent with the rules of regulation foot-ball.

llt will be seen from the above description that l have provided a novel form of football game which differs widely from any heretofore employed in that it comprises a plurality of team charts of teams possessing different elements of strength and weakness, as well as a. plurality of sets of such charts illustrating important features of the game. The interest in the game is greatly enhanced by the provision of substitute charts by which under certain conditions, substitute players may be put into a team which may or may not provide a new element of strength for a certain specified play or as a general source of strength for a team which is obviously weak. lt will also be noted that the game follows in all respects regulation foot-ball and may be employed advantageously to teach the players or others various features of the game as well as developing the faculty of analyzing plays and deterA mining the proper plays to employ in order tol successfully gain against the opposition.
